The missing worker was last seen working near the grain bin at the facility at 1250 Chicago St. in Milton. The man was reported missing at 10:20 a.m., according to police.

More than 16 emergency crews attempted to rescue Guell over 12 hours, according to the statement.

"There are no words to describe the sadness I feel about the events that have happened today," Mike Opdahl, manager of ethanol operations for United Ethanol, said in a statement.

Opdahl said employees train to prevent accidents. Milton police and officials with the Occupational Safety and Health Administration plan to investigate.

Guell was an employee at the company for seven years and is survived by his wife and young son.

"Please keep us all in your thoughts and prayers as we work with emergency services to piece together today's activities, and most importantly, as we mourn the loss of this beloved family member, our fellow employee and friend," Opdahl said.
